I guess, you should try to ping or traceroute to contextgarden.net from terminal. the IP is different for www.contextgarden.net , which is probably what the browser looks for. Ping gave this: 33 context-47: ping contextgarden.net PING contextgarden.net (193.2.4.200): 56 data bytes .. 64 bytes from 193.2.4.200: icmp_seq=27 ttl=49 time=39.023 ms 64 bytes from 193.2.4.200: icmp_seq=28 ttl=49 time=38.522 ms ^C --- contextgarden.net ping statistics --- 29 packets transmitted, 29 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 37.669/38.526/39.896/0.656 ms What now.
